安装ubuntu 16.04 LTS 关于swap
chr*_*o.1 8 live-usb partitioning dual-boot swap system-installation
如何避免重新格式化其他交换分区？
我的硬盘中有很多发行版：
- 视窗10
- Ubuntu16.10
- Antergos[ Arch Linux]
- Fedora25
- 可用空间
- 数据
所有 Linux 发行版都有交换分区（每个 16GiB）。
在可用空间中，我首先创建了一个 16 GiB 的交换分区，其余大小用于根分区（ext4）。
- /开发/ sda13
- /开发/ sda14
奇怪的是我们不能选择交换分区，无论如何点击“立即安装”按钮
我不想重新格式化那些Linux的swap，如何避免？

不同系统不需要不同的交换分区，就像不同系统不需要不同的内存条一样。只需在他们所有人之间分享一个。您应该使用最左边的一个，因为它是读/写速度最快的一个（在 HDD 上）。
关机后唯一的相关内容仍在交换中是当您休眠 PC（挂起到磁盘）时。但无论如何，这是默认禁用的。
不要在意它们被格式化。如果没有系统挂在磁盘上（并且仅当使用交换分区来保存挂起映像时，这不一定是这种情况），它不会更改任何内容。
如果交换分区是使用其 UUID 自动挂载的，则格式化交换分区是一个问题。要检查是否是这种情况，请打开/etc/fstab系统文件。如果有一行包含以 开头的单词“swap” UUID=，则必须用新的 UUID 交换 UUID。请注意，不必有这样的行。您的交换分区可以通过它们的设备名称来识别。在这种情况下，例如，该行以 开头/dev/sda12，无需执行任何操作 - 除非您删除了分区，或者它现在是不同类型的分区，在这种情况下，必须更改设备名称。
如果您删除了除一个交换分区之外的所有分区，请将相同的 UUID 写入/etc/fstab所有 Linux 系统的相应行。这可以在实时会话中或在系统本身中完成。更改将在您下次启动后生效。如果 UUID 改变，swap 分区将不会被挂载，但除了没有 swap 分区外，系统可以正常使用。
